Karlovic, Ancic out US Open
New York - Croatians Ivo Karlovic and Mario Ancic have withdrawn from the US Open because of injuries, the US Tennis Association said on Monday.
Karlovic, a former top-15 player now ranked 63rd, had surgery on his left Achilles' tendon and hasn't played since the Madrid Masters in May.
The US Open is the third consecutive Grand Slam tournament he'll miss after entering 26 in a row.
Ancic has a back injury and will be skipping a seventh straight major championship.
He has been ranked as high as seven in the world but has tumbled to 469th. Ancic had been given a berth in the US Open based on a protected ranking of 65th. He last played on tour in May at Munich.
The withdrawals mean that Jamaica's Dustin Brown and Germany's Tobias Kamke move into the main draw.
The US Open, the final Grand Slam of the year, starts on August 30 at Flushing Meadows.
